I had an air tool that rarely use and didn't bother oiling it. A couple minutes into using it I felt air coming out where that pressure adjustment screw is. Then about 30 seconds later it completely came out. Makes me wonder if oiling them helps them stay in place better. It's not really a good design, but they all seem to have that same design. It's just a hollow bolt that has the end of the threads holding the oring against a flat bore in there. Not really much surface area to hold it in. All I did was unscrew it and put it back in. Seems to be holding fine now.
